HYDRAULIC PUMP.

SPECIFICATION forming part of Letters Patent No. 384,050, dated June 5,1888.

Application filed January :23, 1888. Serial No. 261,672. (No model.)

.To all whom it may concern:

- Beit known that I, JOHN HULL MARTIN, of Oroville, Butte county, Stateof California, have invented an Improvement in Hydraulic Pumps; and Ihereby declare the following to be a full, clear, and exact descriptionof the same. My invention relates, broadly, to hydraulic gravel-mining,and particularly to a pump by which an excavation can be readily madeiuthe ro sink or workings down to the bedrock, preparatory to applying theordinary hydraulic elevator, said pump being further adapted for use inriver gravel-mining, acting itself as an elevator.

An elevator of the ordinary type-such as shown in Patent No. 277,762,issued to meA May l5, lS-cousists of a discharge-pipe the lower end ofwhich is set down into an eX- cavation in the workings, and the upperend 2o is in communication with the flume or rests on the foot dam ortop of the breast above. In the open lower end of this pipe is littedthe nozzle of the supply-pipe by which water under pressure is directedinto the inclined discharge-pipe, the water serving to force thematerial up through the discharge-pipe, said material being first washeddown into the excavation by means of a powerful stream of water directedupon it in the surrounding 3o workings by a hydraulic engine or nozzle,commonly known as a hydraulic giant. In ordinary cases the excavation inwhich the lower end of the elevator or discharge-pipe rests must befirst made by digging in the usual manner and throwing up and disposingof the stut'f and water which accumulates by asuitable means-such as byshovels, wheelbarrows, and ordinary pumps.

My invention has for its object the provis- 40 ion of a pump which is soconstructed as to make and clear its own excavation, and which can alsobe used in riveiemining, as it will raise the water and gravel highenough to run through ilumes and gold-saving devices.

My invention consists, essentially, in a discharge-pipe to be set at aninclination with its lower end in the workings, a nozzle so jointed tothe lower open end of the dischargepipe as to permit said pipe to changeits in` 5o clination, and a sectional supply-pipe with movable orflexible joints connected with the nozzle and supplying water underpressure.

The operation of this pump will be better understood after a moreparticular description of its construction. 5 5

Referring to the accompanying drawings, Figure l is a side elevation ofmy hydraulic pump. Fig. 2 is a vertical section ofsamel A may besupposed to be generally the gravelworkings or sink,- and B is the flumeor 6o other receptacle above, being on the eleva tion to which it isdesired to raisethe material in the sink.

Gis the discharge-pipe, the upper end of which rests upon the flume andthelower end 6 5 rests upon the ground below. The lower end of thedischarge-pipe O is open, and has connected with it, by the bolts c, thenozzle D, which, as shown in Fig. 2, consists of a iixed portion, d,forming a bearing, and a curved 7C movable portion, d', fitted intheiixed portion and movable therein, though held in position in suchaway that,no matter how it may turn, its stream of water is directedcentrally and perfectly parallel with the walls of the dischargepipe.

The nozzle D is connected with a supplypipe, E, which is made insections with flexible or movable joints e, constructed in any suitablemanner to allow each section to vary its inclination as needed, thesejoints being preferably similar in construction to that by which thenozzle is jointed to the discharge pipe. The supplypi pe may be supposedto be connected with a suitable source of water, so that water underpressure is directed through it and through the nozzle into thedischargepipe.

In operating this pump it is properly set,in the first instance. Ahydraulic nozzle or giant go of ordinarykind :is then used todisintegrate the material in the workings directly under and around thelower end of the dischargepipe. This material finds its way vinto theopen lower end of the discharge-pipe, and is thence forced on up by thewaterunder press ure directed from thenozzle of the supply-pi pe,

and as the excavation caused by the operation of the giant and thedisposal oi' the material by the pump goes on, the discharge-pipe C va:ce

ries its inclination, itslower end sinking down, the joint at the nozzlepermitting it, and the supply-pipe itself being jointed, its sectionschange their inclination as the giant washes out the stuff under andaround them, so that the whole apparatus goes down as the exea` vationproceeds, and at the same time the material of said excavation is forcedupwardly and carried away by the pump. It will be seen, therefore, thatthe excavation is thus made of the necessary depth down to the bedrockwithout the use of ordinary digging and ordinary disposal of material.

It is obvious that the pump herein described may be considered as anelevator itself, and may be used as such in river-bottoms and otherplaces, or may be used onlyr for the 'purpose of pumping water out ofthe sink.

Having thus described my inventiomwhat I claim as new, and desire toprotect by Letters Patent,is-

1. A hydraulic pump consisting of a discharge-pipe having an open'lowerend and a nozzle for directing a stream of water under pressure intosaid open end, said nozzle'having a xed and movable portion whereby theinclination of the pipe may be varied, substantially as described.

2. 'A hydraulic pump consisting of a dis charge-pipe having an openlower end,a iiexible pipe for conveying water under pressure, and anozzle connected with the supply-pipe, and with the lower open end ofthe dischargepipe, said nozzle consisting of a fixed and a movableportion, forming amovable joint, whereby the discharge-pipe andsupply-pipe may change theirinclination, substantially as hereindescribed.

3. A hydraulic pump consisting of a discharge-pipe having an open lowerend, a'sectional supply-pipe provided with leXible or movable joints forconveying water under pressure, and a nozzle for said supply-pipeconnected with the discharge-pipe, said nozzle consisting of a fixed andmovable portion, forming a flexible joint, whereby both pipes mayautomatically change their inclination, substantially as hereindescribed.

4. In a hydraulic pump, the combination of the inclined discharge-pipe,the flexiblyjointed supply-pipe, the ilexiblyjointed nozzle, and thebolts connecting the nozzle with the discharge-pipe, substantially asherein described.

In witness whereof I have hereunto set my `hand.
